RFR 8196908: (ch, fs) Safe publication of monitor objects and some others

[Pavel Rappo]

Hello,

Please review the following change:

 http://cr.openjdk.java.net/~prappo/8196908/webrev.00/

This change addresses a number of issues with safe publication and covers some
trivial typos. It seems that there are more similar issues in that area.
However, I believe it is better to be rather conservative and firstly address
issues that are pretty straightforward.

Thanks,
-Pavel
